ADDITIONAL ADDRESSING INFORMATION:
Responders need to be able to see the numbers quickly, clearly, and definitively to expedite their response. Also, remember that your address may be used as a reference point for responders to find the appropriate address they are responding to, even if it is not yours.
A helpful way of thinking about posting your address in a visible manner would be, picturing an ambulance trying to find your house at night when it is snowing. What would they be looking for?
“An ordinance establishing an orderly system for naming roads, addressing property, placing road intersection signs, and insuring continuity for future growth in Madison County.”
“A resolution establishing policy for naming and renaming roads in Madison County”
